The clitellum extends over $xii—2xvii = 44; it is well delimited in front 
and behind, is slightly swollen, shows the dorsal pores, and setae are just visible

The male apertures appear as minute white dots each in the centre of a circular 
slightly raised area. These areas touch each other in the middle line, and take up 
the greater part, about two-thirds, of the length of segment xviii; they are white 
with a darker centre. The pores are in the transverse line of the setae, in a position 
corresponding to seta b; the areas ar: void of setae. 
The female aperture is single, a minute dot in a small shallow depression in the 
line of the setae of xiv. 
‘The spermathecal apertures are minute, in grooves 7/8 and 8/0, near the middle 
line, approximately in b. 
There were no other genital markings. 
Internal anatomy.—The first septum is 4/5; none are noticeably thickened. 
The gizzard is barrel-shaped, of considerable size but soft, in segment vi. The 
oesophagus is bulged in xv, xvi and xvii, with transverse vascular striations; on 
opening this portion, small folds are seen projecting into the lumen. The intestine 
begins in xix, behind the prostate. 
The excretory system is micronephridial; the nephridia are relatively few and 
scattered ,—most numerous on the body-wall in the clitellar segments. 
The last hearts are in xiv; these are smaller than those in xiii. 
Testes and funnels are presen: in x and xi (testes not identified in the latter 
segment). Vesiculae seminales are attached to the posterior surface of septa 10/11 
and 11/12; they are racemose in form and each meets its fellow above the 
oesophagus. | 
The prostates are confined to xviii; they are cut up into lobes which are tightly 
compacted together. The duct runs straight inwards to open near the middle line ; 
its first part is narrow, the rest stout ; it has the usual shining appearance. 
The ovaries are large, with moniliform branches. Ovisacs are present in xiv, on 
the anterior septum, each containing six to twelve eggs. I satisfied myself that 
these were not a second, abnormal pair of ovaries; they are sessile on the septum, 
and all the contained ova appear to be of full size. 
The spermathecae (fig. 27) are two pairs, in viii and ix. The ampulla is of a 
flattened ovoid shape. The duct is well marked off from the ampulla, is moderately 
wide, and about +—4 the length of the ampulla. The diverticulum is given off from 
the termination of the duct; it is a long and narrow glistening tube with a slightly 
dilated inner end; it is longer than the ampulla, and when laid alongside it may reach 
beyond the ampulla for a distance equal to the length of the ampulla itself, but its 
length varies. 
There are no penial setae. 
Remarks.— The presence of an additional pair of hearts beyond what is usual 
and the existence of egg-sacs, are peculiarities which mark out the present species as 
occupying an isolated position in the genus.
